ALBUM-CLASP.

SPECIFICATION forming part of Letters Patent No. 252,226, dated January10, 1882,

' Applicationfiled July 5, 1881. (No model.)

To all whom it may concern Be it known that I, JOHN G. KOCH, a citizenof the United States, residing in Berlin, Germany, have invented anImprovement in Album-Clasps, of which-the following is a specification.

Album-clasps have been made in twoparts that are acted upon by a screw,so as to adapt them to different thicknesses of books.

My invention is made with reference to simplicity of construction and torendering the clasp ornamental and preventing the screw being visible ateither side of the clasp.

In the drawings, Figure 1 is a face view of the clasp, partially insection; and Fig. 2 is a section at the line w 00.

The clip-pieces a and 'b, that are to be secured to the edges of thealbum or book-cover, are made of any desired shape so as to be attachedby rivets or otherwise. Upon the clippiece a there is a hinge, c, thatconnects it to to the box 01, that is made preferably'with a removablecap-plate, 2, and guide-slides 3, and e is a sliding frame forming'themovable portion of the extension-clasp. This frame 6 has a bow or loopthat catches over the stud t upon the clip piece b, or connects with anyother fastening on this clip-piece, and said frame 6 also has across-bar, 5, within the box d, and

0 through this cross bar the screw 4 passes.

Said screw can be revolved; but its head 6 at one end and arivet orspread end at the other prevent end movement to the screw. Hence, whensaid screw is revolved by turning the head 6 between the thumb andfinger.,'the.cross- 5 frame 6 is moved to extend or contract the clasp.In this movement the crossbar 5 is moved sidewise, and the parallelportion of the frame slides endwise within the guide-slides 3.

The cap-plate can be fastened on by screws 40 or otherwise, and theclasp can be extended or contracted at pleasure, either to suitdifferent sizes of books or to hold the book closed more or lesstightly.

I claim as my invention- The combination, in a book clasp, of the clipsat and 'b, the box 01, hinge 0, connecting the same to the clip a, theframe 0, having a crossbar within the box, the screw r, also within thebox, and passing through the cross-bar, and having a head, 6, outsidethe boX, by which it can be revolved, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN G. KOCH. Witnesses: CARL NEUE'R, BERTHOLD R01.
